Thanks for the reply SuperDeadite - I literally just won a FMT-412B card on Yahoo Actions with the help of a friend in Japan - I hope it's working as it's sold as junk... (and wasn't cheap!)
When you say about the cable differences, I'm assuming that as it's coming out of the card, I just need to make an adapter with the pinout for RGBHV, rather than RGBS, right?
I'll probably test the Composite first! Am I right in saying that Composite output from the card to a TV would give the same image as a Marty?
On a Fresh series, H and V Sync are on pins 14 and 15, just like NEC/Sharp. But on old Towns and that video card, pins 14 and 15 are not connected. It outputs CSync on Pin 7. Later Towns monitors are actually wired for both.
The Composite/S-video ports will only work when system is running in 15khz. So a low-res only game like Turbo Outrun will work. With 24/31 you will get a black screen. It is not a like a Marty at all.
Hi all,
The video card has arrived today - I installed it and used the included composite adapter to run it on my Sony CRT TV, and it displayed Composite fine, as expected.
However, I can't get it to work on my Taxan 770 Plus LR, though. I opened up the 15-Pin RGB to VGA connector I made previously, and put the wire for Pin 14 to Pin 7, and disconnected Pin 15, and it does not work. I see the FM Towns logo on power on for a second (and it's rolling), then a black screen. Bear in mind this monitor is multi-sync and works on 15kHz, 24kHz and 31kHz on my X68000.
It worked fine previously, when I had it connected to the 15-Pin RGB out of my Fresh-TV, so is it my monitor? Do I actually need to wire it back with Pin 14 and 15 connected, or will this destroy my video card?
I also have my Sony VGA CRT connected to the VGA socket on the back, and it displays the usual image fine, so I know it's not that (as someone asked before - is it OK to have two monitors connected at the same time?) I obviously unplugged it to see if it made any difference to the other screen, and it didn't.
SuperDeadite or anyone else - any ideas?
Thanks,
Paul
EDIT - Had a play with this cable, and no joy - I am wondering if it's because the Taxan 770 Plus LR is a CGA/EGA monitor, and from a look at this pinout, these don't have Csync, just Hsync and Vsync.
The monitor came with a VGA adapter which is what I use with X68000, Amiga and Falcon, and all of these work, but I guess it's because they all use Hsync and Vsync!
How the hell do I go about getting this to display on my nice multisync monitor???
